Landing for mine cages



Feb. 7, 1933. G. HOLMES LANDING FOR MINE CAGES Filed Feb. 27, 1950 Q QANT HOLMES.

ATTORNEY Q forms and the relative movement of the two parts maybebrought about in various ways but, in the present instance, I, haveshown the landing as comprising two separate parts or contact members 14and 15 arranged ln line with the respective contact surfaces 13 of thecage and each having'its lowersur 15 face inclined, as shown at 16. Thelower inclined surfaces of the landing" members '14 and 15 are supportedupon correspondingly inclined surfaces of fixed supporting members 17which, in the present instancejare mounted on timbers18, and may berigidly connected one to the other by transverse bars or plates 21. Theupper surfaces of the supporting member 17 are inclined downwardly andinwardly and the two landingmembers 14 and 15 are so connected one tothe other that when one landing member is forced downwardly on itsinclined support the other will be forced'upwardly on its inclinedsupport. In the construction here shown the two landingmembers areconnected by a rigid bar 19 pivotally, connected at itsiends with therespective landing members, as shown at 20, this bar 'being'in thepresent instance, tubufla'rin form. it will be apparent that should thesupporting members 17 be vertically displaced with relation one to theother, or should there be a lump of coal on the one landing member whenthe latter'is engaged by the cage, the two landing members, will 4automatically position themselves so as to bring the upper surfacesthereof into alinemovement of both sides of the cage. It will beunderstood,of course, that if there is a lump of coal on one landingmember this lump will be crushed but that the powdered coal or apartthereof will remain on the landing member and thus elevate the efi'ective surface of that landing member above the surface of the otherlanding member. As the ,cage approaches the lower limit of its movementit will first engage that landthe landing member will be moveddownwardly by thepressure exerted thereon by the cage until the otherlandingmember [has movedup far enough to engage the opposite side of thecage, at which time the movement of both landing members will be checkedand the downward movement of the cage interrupted.

It is not essential to the operation of the separate one, from the otheror that they should be slidably mounted but I prefer the 'rections. v, HV 3. A landing for a minecage or'the like construction here illustratedbecause it is easier to maintain in an operative condition than would bea construction in which the landing members were carried by a pivotedsupport.

While I have shown and described one embodiment of my invention I wishit to be understood that I do not desire to be limited to the detailsthereof as various modifications may occur to a person skilled in theart.

Having now fully described my invention, what I claim as new and desireto secure by Letters Patent, is a 1. Alanding fora mine cage or thelike, 'comprisingftwo movable parts'arranged in the of the respectivesides of said cage and means controlled bythe downward movem'ent of "oneof said parts to cause a'corresponding' upward movement to b'eimpartedto the other part. a o 2. A landing for a mine'cage or the likecomprising two landing members arranged 'to be engaged by the respectiveside portions of said cage, means forsupporting said land- '90inganembers for inovement'in oppositely inclined planes, and means forconnecting said landing members one to the other to cause them to movesimultaneously inv opposite dicomprising supporting members havingopposltely nclined faces,land1ng members slid- ,ablymounted on theinclined faces of the re- [spect1've supporting members and arranged tobe engaged by the respective side portions of said cage,-andmeans for soconnecting said landing members one to the other that h e e of ne ngmember in one direction Wlll cause the other landing memy I .ber;to movein the other directioni ment and thus simultaneouslyinterrupt the 4.

7. A landing for a mine cage or the like comprising fixed supports,landing members movably mounted on said supports, connected one to theother and arranged to be engaged by the respective side portions of saidcage, said landing members and said supports having cooperating parts tocause both landing members to be held against movement when they aresimultaneously engaged bysaid ca e and to cause said landing members toe moved in opposite directions when one landing member only is engagedby said cage. 8. A landing for a mine cage or the like comprising twoparts mounted for up and down movement and arranged to be engaged by therespective side portions of said cage, and means for causing said partsto be moved in opposite directions when one of said parts is engaged bysaid cage before the other part is engagedby' said cage.

9. A landing for a mine cage or the like comprising supporting members,landing members supported by the respective supporting members for upand down movement with relation thereto and having parts arranged to beengaged by the respective side portions of said cage, and a barconnecting said landing members one to the other to cause them to movein opposite directions.

In testimony whereof, I afiix my signature hereto.
